Asymmetries are the most difficult dentofacial deformities to treat with orthognathic surgery. This occur due the anatomic alterations in mandibular form and contour, sometimes on body, ramus or condyle, or in all. In the most of cases, the first step is the uncoordinated condylar growth. So, some tools to solve this are the osteotomies to recontour the face. It’s known that mandibular growth with asymmetry can result in maxillary alterations, with plan tilted and unaesthetic smile. One of the most likely etiologies to these deformities are the hemimandibular hyperplasia resulting from condylar growth. The orthognathic surgery are a group of techniques performed to correct the maxilla, mandible and menton deformities. In some cases, hig condylectomy are done to prevent postoperative growth. To complement, the osteoplasties to recontour the mandible are done to improve aesthetic to the face. Series of cases are presented with different kinds of osteotomies in mandibular body, ramus and menton. Some cases need high condylectomy associated. The Virtual Surgical Planning (VSP) is an important step and tool to do cases with asymmetries.
